Abstract (en)
In an hydraulic system including an hydraulic master cylinder assembly (1) for normal service braking, a pump (12) is adapted to return the volume of fluid applied to a brake (2) for brake re-application in an anti-lock mode at a rate determined by a solenoid-controlled flow control valve (7) and to provide the necessary pressure to operate a brake on a spinning wheel for traction control. The master cylinder assembly (1) is also connected to the brake (2) through a by-pass circuit (20) by-passing the flow control valve (7) and including a second solenoid-controlled valve (40) responsive to signals from an electronic control module (30) to place the master cylinder assembly (1) in direct communication with the brake (2) upon latching of the flow control valve (7). <IMAGE>
